OMG had I been missing out without it! My back no longer hurts in the morning when getting out of bed, I sleep like a baby now!  I was able to take out the slats from my platform bed, and this fits right inside my frame perfectly! The only thing I had to do was re-run the wire underneath as it was rubbing up against the metal and I didn’t want it to break, but a very easy fix! Love my new bed and the price was the best I could find!
